The trapezoidal block 211 is slidably connected to the inner surface of the movable groove 23, and the spring 29 will stretch as the trapezoidal block 211 moves left and right.

[0038] Reference Figure 5 and Figure 6A through-cutting edge is provided at the rear blade of the knife block 32 , and the plastic rod 37 is located inside the through-cutting edge of the knife block 32 . The knife block 32 can cut the plastic rod 37 when it rotates.

[0039] Working principle: When in use, if the staff operates, first use the key to turn the lock core 28, the lock core 28 will drive the worm 217 to rotate, the worm 217 will drive the worm wheel 216 to rotate, the rotation of the worm wheel 216 will drive the threaded sleeve 215 to rotate, through the threaded connection with the threaded shaft 214, when the threaded sleeve 215 rotates, the threaded shaft 214 will move to the right, drive the U-shaped shaft 213 to move to the right, drive the trapezoidal block 211 to move to the right, at this time, due to the obstruction of the inner sleeve column 27 fixedly connected to the clamping column 26, the outer sleeve column 210 does not move in the left and right directions, and moves to the left relative to the trapezoidal block 211. At the beginning, the spring 29 will be stretched, and when the clamping column 26 passes through the inclined surface of the trapezoidal block 211 When moving downward, the spring 29 will recover. When the trapezoidal block 211 moves to the far right, the clamping column 26 will be pulled to the innermost part by the spring 29 and completely retracted into the clamping groove 22, so as to completely come out from the inside of the bayonet groove 5. At this time, the electric box door 6 can be opened, but the staff must rotate the threaded clamping column 34 to move downward so that the threaded clamping column 34 presses the knife block 32 to fix it in position, and then moves the outer frame sleeve 31 upward to disengage the fixed clamping block 33. At this time, the electric box door 6 can be opened normally. If the electricity thief forcibly opens the door, the fixed clamping block 33 will drive the knife block 32 to rotate and cut off the plastic rod 37, and the weight block 36 will fall along the space framed by the baffle plate 35 and the box body 1, and hit the alarm 310, sounding the alarm.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
